  Hello

  on technet, enable-remotemailbox dont list -shared attribute

  but set-remotemailbox have an attributed name -type

  https://docs.microsoft.com/en-us/powershell/module/exchange/federation-and-hybrid/set-remotemailbox?view=exchange-ps

  -Type
  
  The Type parameter specifies the type for the mailbox in the service. Valid values are:
  
      Regular
  
      Room
  
      Equipment
  
      Shared

  Fair question - I am trying to get the customer to confirm what version they are actually running.

  Hi,

  Is there any update about your issue? What's the server version your customer using?

  We can see the usage about the parameter -shared from the document:

  Note: This switch is available only in Exchange 2013 CU21 or later and Exchange 2016 CU10 or later. To use this switch, you also need to run setup.exe /PrepareAD. For more information, see KB4133605.
  

  The Shared switch specifies that the mailbox in the service should be created as a shared mailbox. You don't need to specify a value with this switch.

  And in the KB mentioned that:

  Exchange Server 2016
  

  To enable the parameter -shared so that it will work, make sure that you prepare Active Directory by running the following command:
  

  <path_to_Exchange2016CU10_or_LaterBuild>\setup.exe /PrepareAD /OrganizationName:”first_organization_name” /IAcceptExchangeServerLicenseTerms
  

  And install the same build of Cumulative Update 10 for Exchange Server 2016 or a later cumulative update for Exchange Server 2016.

  Regards,
  

  Joyce Shen

  Good comprehensive advice here.  I was able to confirm that the customer's environment was not up to the minimum CU10.
